Change derive path

I’ve used bitcoinj wallet and used derive path as below.

public static final ImmutableList<ChildNumber> ACCOUNT_ZERO_PATH = ImmutableList.of(ChildNumber.ZERO_HARDENED);

But I made changes in above path for generating bip44 standard addresses.

public static final ImmutableList<ChildNumber> BIP44_ACCOUNT_ZERO_PATH =ImmutableList.of(new ChildNumber(44, true), new ChildNumber(1, true), new ChildNumber(0, true));

Now As I load wallet in application then it loads from backup and app crashes because it took old derive path and I already changed it.

So it won’t find old derive path and app crashes.

How can I change derive path?

Please help.

Thanks.
